M52348FP
WIDE FREQUENCY BAND ANALOG SWITCH
DESCRIPTION
The M52348FP is an semiconductor IC for RGBHV interface that
switches signals input from two types of image source and outputs
them to CRT display etc. The synchronous signal meets the
frequency band of 10 kHz to 200 kHz and is output with TTL. The
IC adopts 250 MHz for the frequency band width of video signal,
providing high resolution images. It is optimum as an IC for
interface with various types of new media including high resolution
CRT.
FEATURES

9. As in the same manner, find crosstalk between 2 pints in
response to input into pin 13 and pin 16 only.
C.T.I.3 Crosstalk 3 between 2 inputs
C.T.I.4 Crosstalk 4 between 2 inputs (100 MHz)
Specify input signal to be SG4. In the same manner as in C.T.I.1
and C.T.I.2, find crosstalk C.T.I.3/C.T.I.4 between 2 inputs.
C.T.C.1 Crosstalk 1 between channels
C.T.C.2 Crosstalk 2 between channels (10 MHz)
1. The conditions shall be as provided in the Electrical
Characteristics Table. This measurement shall take active probe.
2. Assign SW19 to GND and input signal SG3 into pin 2 only.
Specify the output amplitude of T.P.35 to be VOR5 at that time.
3. In the same status, measure the output amplitude of T.P.30 and
T.P.27and specify the values to be VOG5 and VOB5.
4. When this is the case, calculate crosstalk C.T.C1 between
channels by the following formula:
C.T.C.1 = 20LOG

5. In the same manner, find crosstalk between channels in
response to inputs into pin 5 and pin 7 only.
6. Assign SW19 to OPEN and then input signal SG3 into pin 11
only. Specify the output amplitude of T.P.35 to be VOR6 at that
time.
7. In the same status, measure the output amplitude of T.P.30 and
T.P.27. Specify the values to be VOG6 and VOB6.
